On x86-32, this warning now appears for me in 2.6.30-rc3, and did not 
appear in 2.6.29.

drivers/acpi/acpica/tbfadt.c: In function 'acpi_tb_create_local_fadt':
/spare/repo/linux-2.6/arch/x86/include/asm/string_32.h:75: warning: 
array subscript is above array bounds

lspci, dmesg and .config attached.

P.S.  It is unclear in MAINTAINERS whether x86@kernel.org should be CC'd 
in addition to the other addresses listed, or as a replacement for 
individual emails.
